Vorinostat (SAHA) is a pan-histone deacetylase (HDAC) inhibitor (IC50=10 nM) with inhibitory activity against HDAC1 2 3 6 7 11. Vorinostat has antitumor activity, induces cell differentiation, blocks the cell cycle and induces apoptosis.

PTACH (Cpd 51) (NCH-51) is a SAHA-based inhibitor of human HDAC. It can potently inhibit the growth of various human Y cells (EC50: 1 to 10 μM).

SAHA chloroalkane T1 is a novel compound formed by combining Vorinostat (SAHA) with a chloroalkane capture tag, referred to as T1. This innovative approach involves tethering the SAHA molecule with the T1 tag, resulting in the formation of SAHA chloroalkane T1.

4-Iodo-SAHA (1k), an orally active inhibitor of both class I and class II histone deacetylase (HDAC), exhibits EC50 values of 1.1, 0.95, 0.12, 0.24, 0.85, and 1.3 μM for Skbr3, HT29, U937, JA16, and HL60 cell lines, respectively. This compound holds potential for cancer research purposes [1].

Suberoylanilide hydroxamic acid (SAHA) is a class I and class II histone deacetylase (HDAC) inhibitor that binds directly to the catalytic site of the enzyme thereby blocking substrate access. SAHA-BPyne is a SAHA derivative with a benzophenone crosslinker and an alkyne tag intended to be used for profiling HDAC activities in proteomes and live cells. Such terminal alkyne groups can be used in linking reactions, known as click chemistry, characterized by high dependability and specificity of azide-alkyne bioconjugation reactions. SAHA-BPyne labels HDAC complex proteins both in proteomes at 100 nM and in live cells at 500 nM and demonstrates an IC50 value of ~3 μM for inhibition of HDAC activity in HeLa cell nuclear lysates in an HDAC activity assay.

Suberoylanilide hydroxamic acid (SAHA) is a class I and class II histone deacetylase (HDAC) inhibitor that binds directly to the catalytic site of the enzyme thereby blocking substrate access. [1] coumarin-Suberoylanilide hydroxamic acid (c-SAHA) is a SAHA derivative where the anilino cap group is replaced by 7-amino-4-methylcoumarin to produce a fluorescent probe that competitively binds HDAC. [2] The fluorescence excitation and emission maxima of free c-SAHA is 325 and 400 nm

Perfluorinated SAHA is an HDAC inhibitor for use in cancer treatment regimens, with demonstrated greater antiproliferative properties than SAHA . PFSAHA has also been shown to have higher selectivity for PA3774, an HDAC-like enzyme from P. aeruginosa, as well as other HDACs, which may prove beneficial for developing novel chemotherapeutic treatments for cancer.

SAHA-OH, a selective HDAC6 inhibitor with an IC50 of 23 nM, exhibits a 10- to 47-fold greater selectivity for HDAC6 over HDACs 1, 2, 3, and 8. It demonstrates anti-inflammatory effects and reduces macrophage apoptosis [1].

F-SAHA, an HDAC inhibitor (HDACi), and its derivative labeled with 18F are utilized in tumor imaging studies.

Sahandol shows antiprotozoal activity against P. falciparum and T. brucei rhodesiense.

Top HDAC-IN-3 (Compound 31) is a dual inhibitor of Topoisomerase and HDAC with oral activity. It induces DNA damage by elevating reactive oxygen species (ROS) levels, consequently inhibiting the clonal formation and migration of cancer cells, and triggering apoptosis (Apoptosis) and cell cycle arrest. Top HDAC-IN-3 demonstrates a significant antitumor effect in NSCLC models, exhibiting a tumor growth inhibition (TGI = 77.5%, 100 mg kg) superior to that of the HDAC inhibitor SAHA and the combination of SAHA with the topoisomerase inhibitor Irinotecan.

7-Bromoheptanoic acid is a building block.1,2It has been used in the synthesis of azide-based nicotinamide phosphoribosyltransferase (Nampt) inhibitors with anticancer activity and SAHA derivatives that inhibit histone deacetylases (HDACs). 1.Colombano, G., Travelli, C., Galli, U., et al.A novel potent nicotinamide phosphoribosyltransferase inhibitor synthesized via click chemistryJ.

BPR1J-340 is a potent and selective FLT3 inhibitor with potential anticancer activity. BPR1J-340 was identified as a novel potent FLT3 inhibitor by biochemical kinase activity (IC50 approximately 25 nM) and cellular proliferation (GC50 approximately 5 nM) assays. BPR1J-340 inhibited the phosphorylation of FLT3 and STAT5 and triggered apoptosis in FLT3-ITD(+) AML cells. The pharmacokinetic parameters of BPR1J-340 in rats were determined. BPR1J-340 also demonstrated pronounced tumor growth inhibition and regression in FLT3-ITD(+) AML murine xenograft models. The combination treatment of the HDAC inhibitor vorinostat (SAHA) with BPR1J-340 synergistically induced apoptosis via Mcl-1 down-regulation in MOLM-13 AML cells, indicating that the combination of selective FLT3 kinase inhibitors and HDAC inhibitors could exhibit clinical benefit in AML therapy.

MHY219 is a novel HDAC inhibitor. MHY219 induces apoptosis via up-regulation of androgen receptor expression in human prostate cancer cells. MHY219 was shown to enhance the cytotoxicity on DU145 cells (IC50, 0.36 μM) when compared with LNCaP (IC50, 0.97 μM) and PC3 cells (IC50, 5.12 μM). MHY219 showed a potent inhibition of total HDAC activity when compared with SAHA. MHY219 increased histone H3 hyperacetylation and reduced the expression of class I HDACs (1, 2 and 3) in prostate cancer cells. MHY219 effectively increased the sub-G1 fraction of cells through p21 and p27 dependent pathways in DU145 cells. MHY219 significantly induced a G2 M phase arrest in DU145 and PC3 cells and arrested the cell cycle at G0 G1 phase in LNCaP cells. Furthermore, MHY219 effectively increased apoptosis in DU145 and LNCaP cells, but not PC3 cells, according to Annexin V PI staining and Western blot analysis. These results indicate that MHY219 is a potent HDAC inhibitor that targets regulating mu......
